how many Boeing/Douglas/Lockheed airliners have suffered multiple pitot clogging from ice?
Offhand, I can think of a B with a bad result, but that was a switchology problem.
I suspect that the question is better asked from the FBW/ Non-FBW perspective.
There are differing dependencies as mentioned earlier.
Does anyone know of a FBW airliner that does not use airspeed in the control gain calculations?
Isn't comparing windshield and pitot heating like comparing apples and oranges? Very different systems, performing different functions with different operating principles.
